AGE/VT United States Patent 3,443,346 WINDOW CONSTRUCTION Walter S. Eggert, Jr., Huntingdon Valley, Pa., assignor to The Budd Company, Philadelphia, Pa., a corporation of Pennsylvania Filed Aug. 7, 1967, Ser. No. 658,897 Int. Cl. E06b 1/04; E04b 1/62 US. Cl. 52214 1 Claim ABSTRACT OF THE DISCLOSURE Prior to this invention windows of railway passenger cars have normally been incorporated within a sash framework. The sash framework in turn has been fitted within a window sash opening formed within the primary sideframe structure of the cars. A disadvantage of such construction is the necessity for maintaining accurate dimensional tolerances not only of the sash framework per se but also of the primary structure of the sideframe defining the sash frame opening.

It is an object of this invention to provide an improved window construction which avoids one or more of the disadvantages of the prior art arrangements.

Another object of this invention is to provide a window construction which minimizes the dimensional tolerances required between complemental assembled members.

A further object of this invention is to provide an improved window construction which is designed to minimize or eliminate visible fastening means for improved appearance.

For a better object of the present invention together with other and further objects thereof, reference is bad to the following description taken in connection with the accompanying drawing and its scope will be pointed out in the appended claims.

In the drawings FIG. 1 is a vertical elevational inside partial view of sideframe of a railway car, and illustrating the various framing members defining a window opening;

FIG. 2 is a vertical elevational view similar to FIG. 1 but including the addition of a plurality of block-like elements disposed about the margins of the window opening;

FIG. 3 is a vertical elevational view illustrating a decorative trim ring adapted to be received within the opening of the window framing shown in FIG. 2;

FIG. 4 is a partial vertical elevational view illustrating the trim ring of FIG. 3 positioned in place within the opening of FIG. 2;

FIG. 5 is a vertical elevational view illustrating a flexible glazing member adapted to be positioned on the projecting blocks to encircle the window opening of the frame structure shown in FIG. 4;

FIG. 6 is a vertical elevational view of the completed, installation, partially in section, and showing inner and outer windows retained in place; and

FIG. 7 is an enlarged cross-sectional view taken along the line 77 of FIG. 6.

Referring to the drawings, wherein like numerals indicate like parts unless otherwise specified, and particularly to FIGS. 1 and 7, a sideframe of a railway car is generally indicated at 10. This sideframe constitutes the sidewall construction which extends between the floor and roof of a vehicle and includes a generally rectangular window opening W therein. The opening is bounded by a pair of spaced apart hat section posts 11, 13 and upper and lower window Z-rails 15, -17 extending transversely therebetween. An outer skin sheathing 19 is aflixed to the outer surfaces of the posts and rails and upper and lower inside sheathing 21, 23' to their inner surfaces. Upright filler strips 25, 27 are suitably secured to the inside surfaces of the posts 11 and 13 so as to provide an even planar supporting surface for an interior trim member 29 shown in FIG. 3.

Still referring to FIGS. 1 and 2, it is seen that the lower horizontally disposed window rail 17 includes a plurality of elonagted openings 31 disposed parallel to the longitudinal axis of its horizontal flange 33. These openings permit the upward flow of air passing between the inner and outer sheathing 23, 19 respectively. Fastena ing means in the form of a plurality of elonagted block elements 35, as seen in FIGS. 2 and 7, which may be of plastic or other lightweight structural material, are secured in upstanding relation on horizontal flanges '33 of rail =15, 17 but spaced a slight distance laterally from vertically disposed flanges 40 and 41 of said rails. In addition, vertically disposed blocks 35 are also in a like manner, secured upon sidewall flanges 42, of vertical posts 11 and 13 respectively. As seen in FIG. 7, block 35 is secured by means of a screw 45, passing through a hole in the block and anchored to horizontal flange 33. The remaining blocks disposed about the periphery of the window opening may be secured in a like manner.

Upon installation of the blocks 35 around the margin of the window opening W, as above indicated, the aforementioned decorative trim frame member 29' of FIG. 3 which is generally of rectangular form, is thereafter inserted in place as seen in FIG. 4. The trim frame is shown as including a vertical planar edge flange 47 which overlaps the upper and lower inner sheathing 21, 23 and vertical strips 25, 27. The frame 29 also includes an interior ring-like flange portion 49 disposed at right angles to its edge portion 47. The interior trim frame may be drawn in and secured, in place by screws 53 passed through vertical flange 49. The lower horizontally disposed portion of flange 49 includes a plurality of apertures 51 which are aligned with the openings 31 in rail 17 to permit a flow of air therethrough. Thereafter a flexible glazing strip 57 shown in rectangular configuration, as best seen in FIG. 5, is inserted in place upon the spaced blocks 35. The glazing strip 57 may be of rubber-like material. As seen in FIGS. 5 and 7, the glazing strip includes a longitudinal groove 59 extending about its outer periphery of 5 a width to accommodate the blocks 35. The latter blocks serve to press the outside face of the strip into tight engagement with the inner face of flanges of the rails 15, 17. The opposite inner peripheral surface includes a slot 61 to receive the window unit consisting of inner and outer windows 62, 63 bonded in spaced relationship to one another. -A suitable body sealing compound 64 may be applied between the outer face 65 of the strip and the flange 41 of the rail. In addition, the glazing strip may include a protuberant bead 67 which extends outwardly from the upper edge of face 65. The side of the strip which lies opposite face 65 includes a downwardly inclined flange portion 69 which overlaps the top edge surface of flange 49 of trim frame 29. The same side of the glazing strip as that containing flange 69 is grooved to receive a removable inlay strip 70 thereby permitting easy removal and insertion of the unit containing windows 62, 63 in their respective slots.

From the foregoing it can be seen that the above-described structure facilitates the relationship of the interior trim of the vehicle by eliminating the necessity for rigid sash framing and by having the prime structure serve in lieu of the sash framing. The weight and cost of the sash elements are saved thereby serving to improve the sideframe structure.

What is claimed is:

1. A window construction for a wall unit having external sheathing and defining a window opening of a vehicle, comprising, fastening means secured about the peripheral margins of said window opening, flexible glazing strip means coacting in gripping relationship with said fastening means and coasting with said unit, window pane means received within said flexible glazing strip means, said fastening means including a plurality of block means disposed about the periphery of said window opening, said glazing strip being grooved to grip said block means, said flexible glazing strip including a bead-like protuberance overlaying said external sheathing, saidwall unit including internal sheathing, apertured trim means overlaying said internal sheathing, and said glazing strip including flange means overlaying said trim means.
